Vaadin session cookie in iframe

Hi,

My Vaadin applications will be embedded into the customers websites via iframes, but hosted on my servers.
Browsers like Safari don’t allow setting cookies when running in an iframe. Is it possible to use the session cookie by adding a session id to the URL?

Thanks,
Roland

I found http://dev.vaadin.com/ticket/3228 now, and I am surprised that I am (almost) the only one having this problem
